Here in this blog, Codeavail experts will show you what competitive programming is, how to learn, and improve competitive programming skills.
If you want to take your programming language to the next level, you should have a strong mathematical background. Each super-programmer has a very strong mathematical background. And because of this, they can solve complex problems very easily and in the complexity of low space and time.
Although you need to put different arguments behind every problem, mathematics works like an inspiration. You need to practice a lot to get good and competitive programming skills.
1. Fully understand
First, study all the concepts of the programming language in depth. Always use standard books. There are many online platforms available today where computer experts around the world share their knowledge and try to make concepts easier.
2. Follow this approach
Try to start coding using simple problems. Before writing the code, create a flowchart of the logic that is being used first. This will increase the number of correct codes that will not only enhance your skills but also enhance your confidence.
3. Real-life implementation
Once you get accustomed to code and try to create basic programming codes that solve the problems of your daily life. These may include report cards of any student, ticket reservation system, library management system, etc.
They will make you feel like a software developer.
4. Brief code
Now the next step is to shorten the code. Let's say you create a simple code for the library management system. Now try to cover it so that the same work can be accomplished in a very simple and small way.
You can only see the problem first and create your own code. Now see the optimal solution to know how it can be reduced.
This is the most important and transition phase from basic programming to competitive programming.
5. Be a fighter
Now start participating in coding competitions. Competitions can take place at your school, online or nationally. Here you will find people as if you are killing and killing each other.
Here, you have to write the optimal solution and that too within the shortest time. Since it is a competition, it is the survival of the fittest. Such a healthy competitive environment accelerates the learning rate and involves learning through fun mechanisms.
In addition, you will also get a rating according to the successful presentation of your code and the competitions you win, which strengthens your professional profile.
6. Start sharing knowledge:
Once you become a good programmer, do not keep your knowledge to you. Spread. Share it with your juniors, your peers and the world.
7. Stay updated
"Success is not the destination for you, it is a way of living life. Therefore, always stay updated on new arrivals in the field of new technologies and coding. This will help you to produce better and provide better service.
Beginners (over 2 months)
For beginners, it is important to learn basic concepts. Participation in many competitions will not help.
An important DS/Blog from a book or blog. Algo. Read about some concepts.
Find a question that can be solved using that concept.
Code and submit.
Repeat 1 - 3.
Medium level competitors (2 to 10 months)
You already know the basics here that help participate in a real competition (especially long challenges).
You should learn to solve the problems that require an understanding of many concepts.
Participate in competitions. Try to resolve the problems.
Read editorials and solve problems that you can't solve during the contest.
Read other tips and learn different tips and tricks.
Learn and hack all small customizations to reduce implementation time.
Pro (less than 12 months)
You are already good at the moment.
Participate in teams. Learn the weakness of your team members. Bridging the gap.
Participate in many small competitions. Reduce the implementation time.
Learn the most advanced concepts and corresponding math. You should try to solve the toughest problems in competitions at this point.

What is competitive programming?
Definition
Competitive programming is to find the best solution to well-defined problems by writing computer programs under specified limitations.
Based on the above definition, there are three aspects of competitive programming:
Well defined problems: you are presented with one or more problems. The problem details include variables, and you should be able to respond to the problem when you return any possible combination of variable values. The problem will be well defined: you will be informed of the exact constraints of all variables, any necessary assumptions, etc.
Computer programs: You resolve the issues that you write to computer programs. The command-line program reads the values of variables from standard input and should write answers on standard output.
Specified limitations: Your program must respond within a specified time and memory limit. In addition, you should write programs in a set of programming languages.
1. Learn a well-known programming language:
You can do competitive programming in any programming language, but it is highly recommended that you have a C/C++ programming language. Select one of the C++ or Java programming languages. This is because execution time is an important factor in competitive programming and therefore, choosing a language whose execution time is fast is going to benefit you.
C Programming Language / C++ programming language and Java programming language are relatively fast, especially when compared to languages such as Python programming language.
2. Starting with competitive programming:
Start practicing on various online programming practice sites, it has a great IDE and an amazing beginner program that will help you get started.
Online practice sites have a lot of problems that gradually increase the difficulty and therefore you won't have to face a sudden increase or difficulty and it lets you look at the test case on which you failed the code that will help you create a test case also.
Learning to debug the code for the case on which it failed. As a total start, it's important that you can look at the test case that failed so you can learn how to target such corner cases.
3. Familiarity with data structures
4. Get familiar with the algorithm:
Algorithms are logic that is applied to different data structures to get the desired output.
5. Starting with actual online competitions:
Once you become familiar with the complexities of time and are able to get acquainted with the complexities of online IDE and penalties you can start with current competitions.
6. Practice Practice Practice

How to learn competitive programming?
There are essentially 6 key stages in learning competitive programming:1. Learn a well-known programming language:

BTW, What I said is "HOW", not "WHAT"...
